ABSTRACT:
A film handling device for pulling out and forwarding a leader from a spool of film after the film has been removed from a film cartridge. The spool of film is held in a film guide having an arcuately formed rear portion shaped to receive the spool of film and a forward guide portion composed of straight sections converging towards a forwarding opening. A pair of film forwarding rollers are selectively engageable with the spool of film through cuts formed in the rear portion of the film guide. A detector positioned in the forward portion of the film guide detects the presence of the film leader. Before the presence of the film leader is detected, the film forwarding rollers rotate the spool of film in the film rewinding direction. Then, the direction of the rollers is reversed.
